How many 300 × 300 × 300 mm boxes fit in a 40ft high cube?
300 × 300 × 300 mm boxes of 300 × 300 × 300 mm (also called 30 cm cube boxes) in a 40-foot high-cube container (40HC) — inner dimensions 12,032 × 2,352 × 2,698 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 79% of the space used, 8 layers high, about 11,200 kg (42% of payload). Open this load in the 3D planner →

The answer in detail
A 30 cm cube. Cubes have only one orientation, so the answer is pure grid arithmetic — a good sanity check for any load plan.
Same footprint as a 40GP with about 30 cm more height — the workhorse of e-commerce and consumer-goods shipping because the extra layer of cartons is almost free.
The simple grid estimate is 40 along the length × 7 across × 8 high = 2,240. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (2,240).

Frequently asked
How many 300 × 300 × 300 mm boxes fit in a 40ft high cube?
2,240 300 × 300 × 300 mm boxes of 300 × 300 × 300 mm fit in a 40ft high cube (inner dimensions 12,032 × 2,352 × 2,698 mm), boxes may be laid on any side. That uses 79% of the 76.4 m³ available and weighs about 11,200 kg.
What are the inner dimensions of a 40ft high cube?
Typical inner dimensions are 12,032 mm long, 2,352 mm wide and 2,698 mm high (473.7 × 92.6 × 106.2 in), giving 76.4 m³ of space and a rated payload of about 26,500 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
How much does a full load of 300 × 300 × 300 mm boxes weigh?
2,240 × 5 kg ≈ 11,200 kg, which is 42% of the 26,500 kg payload — so this load is limited by space, not weight.
How was this number calculated?
By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing all six orientations, stacking with at least 80% base support and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.
